Some people always sign the number 1 with the palm forward.

For example, if the hand slowly bounces while moving forward and then turns to the left, it means something like “the person was walking along leisurely and then made a left turn.”

To show interactions with other classifiers, the nondominant hand is often used as this classifier:
